How To Check If an Electric Motor Is Going Bad

How To Check If an Electric Motor Is Going Bad

For centuries, we’ve seen tremendous innovation in industrial operations. Our ancestors worked diligently to find solutions to the sluggish processes they experienced, which ultimately led us to the development of motors and automation. Today, countless companies rely on electric motors to make their operations more efficient. While motors have certainly made significant improvements to the operations of businesses, companies also must maintain their motors to avoid downtime. In order to prevent future downtime and inefficiencies, you must know how to check if an electric motor is going bad. If you know how and what to look for in a motor, you can take action early and prevent your motor from going down and potentially getting damaged. If you’d like to learn more, you can read our comprehensive guide below.

Check the Bearings and Shaft

A motor’s bearings are one of the most common components to go bad. The bearings endure regular wear and tear, so you need to replace them over time. You must check the bearings regularly because if you continue using a motor with worn-out bearings, it can damage the mechanism and reduce the motor’s efficiency.

Bearings are easy to inspect. All you’ll need to do is rotate the bearings to ensure they turn smoothly and freely. Another way to inspect the bearings is by pushing and pulling the shaft that the bearings attach to. The bearings should rotate smoothly and the shaft should be able to move smoothly as well. That said, if you hear any scraping or feel any friction, you might need to replace the bearings. If the friction is minor, the bearings might merely require lubrication.

Inspect the Motor Windings With a Multimeter

Unsurprisingly, the windings of an electric motor are vital to its mechanics. You should regularly inspect the windings for wear and tear, but more importantly, you need to analyze their resistance. First and foremost, you’re going to need a multimeter to test the windings. To begin, set the multimeter to read ohms and then test the motor’s wires and terminal. You should test the windings for a “short to ground” in the circuit and open or shorts in the windings.

To test your motor for short to ground, you’ll need to set the multimeter to ohms and disconnect the motor from its power source. Then inspect each wire and look for infinite readings. Alternatively, if you get a reading of 0, you might have a cable issue. To determine if a cable is bad, you should test each cable individually and ensure none of the leads are touching. Testing individually will allow you to find the cable causing the problem. On the other hand, if each cable is providing an infinite reading, there’s a motor problem, so you should hire a professional repair service.

To test for open or shorts in windings, you should test the T1 to T2, T2 to T3, and finally T1 to T3. Note: some motors will have different markings such as U to V, V to W, and W to U—you can find your motor’s configuration in the user manual. In general, you’re looking for a reading of .3 to 2 ohms. If you end up getting a reading of 0, you should perform the test again to see if you get 0 again. A reading of 0 means you have a shortage in phases. A shortage means the wires short to ground, which usually leads to a break in the wire. If your reading is well above 2, you likely have an open winding. An open winding simply indicates there’s a broken wire.

Test the Power With a Multimeter

Obviously, an electric motor is only as effective as its power supply. You can test the power supply with the multimeter you used in the previous point. The process and ideal ratings for testing power supplies can vary depending on the type of motor. Each motor will have an expected voltage range, and you’ll want to test the wires to ensure they meet those ranges. Your user manual will provide the necessary details for testing power along with a guide. Testing the components of an electric motor get complicated quickly, and it’s easy to make mistakes in the process if you’re not experienced.

Ensure the Fan Is in Good Shape and Secure

Far too many people forget to inspect and maintain their electric motor’s fan. The fan is vital to your motor’s performance because it keeps the motor cool so it can operate for longer periods. As you might suspect, the fan can easily become clogged with dust and debris, which reduces airflow and keeps heat in. Although the outside of the fan may appear relatively clean, there could be dust and debris built up elsewhere that can slow the fan. When you remove the fan cover to clean, you should also test the fan and ensure it rotates freely. Additionally, the fan should remain secure to the motor; otherwise, the fan won’t move properly and the motor will overheat and certainly will go bad eventually.

While some of the preventative measures we mentioned are relatively simple, you still need to know how to check if an electric motor is going bad. Some of the methods for testing a motor may require a professional’s help, and it’s crucial that you have a reliable professional to contact when you need service. That said, there are a lot of motor repair shops out there, and all of them claim to be experts, but few actually are. So how could you possibly know which company to work with? The answer is found in the company’s history, experience, and integrity.

The Advantages of Custom Electric Motors

The Advantages of Custom Electric Motors

A lot of companies try to sell you something they claim to be custom that isn’t actually custom at all––Moley Magnetics doesn’t do that. Our customers love purchasing custom motors from us because we know what we’re doing, have the years of experience to back it up, and guarantee top-quality. If you’re still skeptical, check out some of the advantages of a custom electric motor below.

Peak Performance for Your Specific Application

By far the biggest benefit of having a custom electric motor built is its performance. The only limitations when building a custom motor is your imagination. While standard motors will work in most scenarios, a custom motor blows the standard motors away in performance. Whether you’re working in manufacturing, recycling, or the railroad industry––you probably rely on the efficiency of your motor. If the motor you’re using was built specifically for your application, it’ll be the most efficient motor you’ve ever had.

Reduced Downtime

Like we previously mentioned, a standard motor would probably work but why use a motor that’s good enough when you could use a great motor? A motor that a professional designed for your application significantly reduces downtime because you’re not trying to force a standard motor that’s not necessarily ideal for your application. Between reducing downtime and boosting efficiency, you can count on a custom motor saving you time and money over time.

Custom Motors Are Easier To Use Right Away

Workers don’t have time (and often the knowledge) to adjust a motor’s mounting plates or attach the motor’s cables to the terminals. Because many motors come with a bare terminal at first, manufacturers expect the user to connect the cables themselves, which sometimes leads to damaging the motor. Like we said previously, a custom motor can be whatever you need it to be. That means you can request brackets, gears, or specific cable attachments so your motor is ready out of the box.

As you can see, there are plenty of advantages to a custom electric motor and they’re well worth your investment. In fact, the efficiency benefits alone are likely to pay for itself. Through custom electric motors, your workers will appreciate the value you put on their productivity.

If you’re ready to take the next step towards a high-quality motor, look no further than Moley Magnetics. Our company began as a motor repair shop and we still offer custom electric motor builds, standard motors, and repairs. Contact our team today if you’d like to learn more or request pricing.

Excavator Safety: Everything You Need To Know

Excavator Safety: Everything You Need To Know

Over the years of innovation in industrial equipment, few machines have become more essential than excavators. Whether your company works in construction, railroad, scrap yards, recycling, or a mixture of industries, an excavator is essential. As the sole leader (or one of them) of the company, you’re responsible for your workers. Heavy equipment is necessary to boost a company’s productivity, efficiency, and ability to complete numerous jobs. That said, excavators can lead to serious injuries if you don’t communicate the basics of excavator safety and operation to your team. If you’re looking for a guide that discusses everything you need to know about excavator safety, we’ve got you covered. Read on to learn more.

Every Machine Operator Should Have the Appropriate Certifications

As with any other profession, if workers don’t have a grasp on the fundamentals of their job, they likely won’t be successful. There are several options for workers to receive certifications for heavy equipment operation. Most workers can complete the certification online within a couple of days. It’s crucial for everyone’s safety and your company that only certified workers operate the excavator. A certified worker will understand the do’s and don’ts of excavator operation. For instance, the excavator’s arm should never be overextended unless necessary because it can make the machine unstable. Moreover, an excavator should always operate on inclines and declines slowly; an excavator should never be parallel to the ground’s slant. A certified operator would know how to dig properly and pile materials up away from the workspace, otherwise the ground could cave in. Of course, there are several other fundamentals that your machine operators need to know in order to use the excavator safely. Without proper certification and training, operators are more likely to make mistakes, potentially hurt themselves or others, or damage the machine.

The Excavator’s Cab Is for the Operator Only

Regardless of whether multiple workers have heavy equipment certifications or not, there should never be more than one individual in an excavator’s cab. Overcrowding a cab can obscure the operator’s view and lead to inefficiencies and accidents. Moreover, because an excavator’s cab is only manufactured to fit one-person, additional individuals won’t have a seat belt which should always be worn during operation. Of course, an overcrowded cab is prone to someone accidentally bumping the excavator’s controls which could lead to a much bigger problem.

Inspect the Ground and Work Zone Before Beginning Operation

If your job site requires digging, you must communicate and train workers to walk the work zone prior to working. Additionally, you’re required to call before you dig, whether it’s with an excavator or shovel. Calling 811 prior to excavation can prevent gas or plumbing leaks and electrical or internet downtime. No company wants to be the one that digs and breaks a pipe that affects everyone in the community, especially since it’s easily preventable by a mere inspection and calling first. Of course, you can use an excavator for more than digging applications. If you’re a scrapyard business, digging isn’t a primary task, but lifting and moving ferrous materials like sheet metal certainly is. Even in a scrap yard, excavator operators should make note of any barriers that might get in the way or affect the strength of their magnet. In addition to barriers, many job sites have uneven surfaces that excavators should avoid if possible.

Require Machine Inspection Before and After Use

It’s easy for workers to go about their days and proceed with tasks without inspecting the machine. Whether you’re the company’s owner or the manager on duty (or both), you must ask workers to inspect the excavator before and after use. Most companies develop a checklist and require workers to check each item listed and sign the document when they complete the inspection. There are numerous items you could include on the checklist. Some of the most important items that should be on your checklist include checking the oil, the tracks, and ensuring the attachment is secure.

While these may seem redundant, your checklist should include information like the machine’s lifting capacity to ensure the operator is aware. At the end of the day, the operator should complete the same checklist and make note of any known issues with the machine. Requiring certified workers to complete a checklist consistently holds operators accountable but also helps you make better decisions regarding machine maintenance and keeping track of oil changes, repairs, or problems. Your workers need to know that the excavator is a vital piece of equipment for the business and their career. That said, the checklist can help you manage and improve your team appropriately. If one worker consistently reports problems with the machine on their checklist but no other operator does, that first worker may be operating the machine poorly and may require additional training.

Supply Your Team With High-Quality Attachments

While your company might primarily use one attachment more than others, most businesses can benefit from having several excavator attachments. A construction company, for example, may primarily use a standard bucket for lifting and digging, but they could also benefit from other attachments like a magnet or a grapple. Whether you need an excavator magnet, grapple, or shears, you must ensure all components are high-quality. Your workers are the backbone of your company and they deserve the best equipment available. Attachments endure more wear and tear than most people realize, and low-quality attachments can fail and result in dangerous accidents. Investing in high-quality attachments upfront reduces the risk of attachments breaking down prematurely on the job, in addition to avoiding excessive repair costs.

Whether you’re a new company or you’ve been in the market for decades, safety is priority above all. Regardless of your experience, our guide includes what you need to know about excavator safety. Of course, there’s plenty more to know, so you should be familiar with your excavator’s user manual for details regarding maintenance, safety tips, and proper operation.

If you’re in the market for the best excavator attachments, look no further than Moley Magnetics. Our family-owned business consists of seasoned industry professionals with over twenty years of experience.

Importance of Magnetic Separators in Food Processing

Importance of Magnetic Separators in Food Processing

Few industries affect the vast majority of society like the food-processing industry. When a business has an impact on such a large number of people, several safety protocols must be in place. In the case of food processing, safety and quality are of the utmost importance because your products affect people’s health, wellness, and nourishment.

There are many ways to ensure high-quality products in food processing, but it all starts with eliminating the risk of contamination. Contamination is unacceptable in most industries, but especially when handling food products. Ferrous particles are one of the most common contaminants in food plants, and you can easily remove those particles with a magnetic separator. As one of the decision-makers at your company, you must understand the importance of magnetic separators in food processing. If you’d like to learn more, our experts have you covered in the guide below.

Magnets Catch Impurities That We’d Otherwise Miss

You may be wondering how ferrous materials and particles find their way into a food-processing plant. Metal particles and shavings can come from a number of sources. One possible source is a farmer’s metal harvesting equipment because particles can chip off the shovel’s blade and end up in the shipment. Another possible source is your facility. You likely have several pieces of moving machinery where nuts and bolts can rattle loose and end up in your preparation or mechanical processing lines. In each of the previous scenarios, there’s a good chance that processing workers would miss the contaminant because of its small size. A magnetic separator would likely attract the contaminant before a worker even noticed something was off.

It’s Better To Reduce Contaminants Early and Prevent Future Problems

Many food-processing plants use magnetic separators at the beginning of their process in an attempt to remove the contaminants right away. Additionally, some facilities will have magnetic separators in the beginning, middle, and end of their process. Either way, it’s important that you have at least one magnetic separator. Additionally, eliminating impurities is vital to a successful business because your customers want to know your facility is clean. If you ship a product with contaminants, customers will end up sick. If customers become sick, recalls and lawsuits are in your future.

The bottom line is you must protect the safety and well-being of your customers (or your clients’ customers). You can’t consider the importance of magnetic separators in food processing without looking at the future of your business. Nobody wants to do business with a food manufacturer that doesn’t take the purity of their goods seriously.

Whether you merely need a magnet or an entire magnetic separation setup, Moley Magnetics has you covered. We take immense pride in the high-quality products we provide our customers, and we know our products will meet and exceed your expectations. If you have questions or would like to request pricing from Moley Magnetics, contact our team today.

Tips for Choosing an Excavator Demolition Attachment

Tips for Choosing an Excavator Demolition Attachment

Demolition is a necessary step in construction, but also in scrap yards and recycling facilities. While our ancestors handled demolishing projects by hand, today we use heavy equipment such as excavators, back hoes, and skid steers because it’s much more efficient. Though heavy machinery isn’t quite enough for our daily operations, we also require several attachments for various uses, one of those being demolition. Unfortunately, in the past, many companies either didn’t have the right demolition attachments or didn’t know what to look for in a quality attachment––until now. In the following guide, our experts break down several tips for choosing an excavator demolition attachment. Read on if you’d like to learn more.

Not all attachments are created equally, have a variety

Depending on your company and the type of demolition you perform, you might need all of the following attachments or you might only need just one or two. In construction and structural demolition, many companies merely demolish buildings with the standard excavator bucket. While the bucket is fine for that application, it’s not the only useful attachment. Some of the other important demolition attachments include grapples and magnets as well. Grapples are a vital attachment for more than demolition, they’re also common in shipbuilding, railroad maintenance, and construction. Every company should have a grapple because they give the machine operator the option to lift items with a reliable and more secure grip.

Far too many companies forget to have a magnet in their attachment arsenal which is a mistake for three reasons. First, after the demolition project, how do you plan on cleaning up the worksite? Additionally, most industries (some more than others) have ferrous materials to clean up and a magnet will make that process much easier. Moreover, unless your company handles ferrous materials, you could sell the materials to scrap yard and earn a profit that you otherwise would’ve thrown out.

Consider the material you’re working with

Much like our previous point, knowing the material you handle primarily will help guide your purchase towards the appropriate attachments. If you’re a scrap yard or recycling facility for example, you’ll certainly benefit from a scrap magnet for a couple reasons. First and foremost, you need to sort materials with like materials, and a magnet will help you perform that task efficiently. Moreover, your facility may receive a vehicle that’s still intact. The easiest and most efficient way to handle a complete vehicle is with the aid of a magnet.

We recognize that not all of you run recycling facilities and scrap yards, though. For those of you working in construction, for example, you might only need the excavator’s bucket and a grapple. Though, we’d encourage you to invest in a magnet as well, because it’s better to have the attachment as an option rather than wishing you had one.

Know your excavator’s specifications

While many attachments are universal and fit on most excavators, that doesn’t mean it will fit for sure. Every excavator has different specifications, so it’s important that you know your specifications prior to investing in attachments. Probably the most important specification know is the excavator’s weight limit. Some attachments are heavier than others and you must ensure your excavator can handle such an attachment. If your attachment exceeds the weight capacity of your excavator, you’re asking for machine trouble. Some of the troubles you’ll experience is your excavator being unstable and performing poorly. Ultimately, if you’re overloading the machine’s weight capacity, the machine might not operate at all if you’re well above the weight limit. Furthermore, an attachment that exceeds the excavator’s specifications requires more work from the machine, which can lead to long term damage, expensive repairs, and more frequent maintenance.

Don’t forget to consider to your power source

Similar to the excavator’s specifications, you must take the attachment’s power source into consideration. Are you planning for hydraulic attachments? If so, you’ll need to know your excavator’s circuit requirements and hydraulic flow rating. If the attachment doesn’t receive adequate oil, it won’t operate at peak performance. Alternatively, those of you interested in magnets might opt for a permanent or electromagnet because it doesn’t require a hydraulic power source, although you might need a generator or battery. Without the appropriate power source, excavator demolition attachments won’t perform as well as they should, and poor performance leads to inefficiencies. Few metrics are more important in demolition than efficiency and productivity, and an inadequate power source will force your attachments to operate poorly and cost your company time and money.

Don’t skimp on quality

As with any company, you’re probably trying to keep expenses low by searching for the best deal possible, and there’s nothing wrong with that. The problem with looking for the best deal is that people often settle for lower quality, and your excavator attachment is no place for mediocre quality. Whether you work in construction, metal recycling, or scrap yards, you know that your equipment is the lifeline of your business, so why would you want unreliable attachments? Your company and your workers deserve to work with high-quality equipment, so invest in quality and invest in your business’s future.

There are several factors to consider when buying attachments for heavy equipment and we get that. To help you make an educated decision that’ll improve your business, we put together this list of tips for choosing an excavator demolition attachment. We’d argue that the most important point on this list after the safety of your workers, is the quality of your attachments.

You shouldn’t take quality lightly because it directly affects your business’s bottom line, the safety of your workers, and the efficiency of a job site. We understand that quality is vital at Moley Magnetics because we have extensive industry experience. Whether you’re in the need for demolition magnets, grapples, or even shears and shredders, we’ve got you covered. Our business is family-owned and we take pride in the work we do and the successful company we’ve built over the years.
